Title: Motion vector calculation device
Inventor: TACHIKAWA TETSUYA
IPC: H04N7/18
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To calculate a motion vector which appropriately expresses the motion of an object by obtaining the motion vector of respective picture points on a picture through the use of a local correlation method, estimating the motion vector of a part where a luminance change is little and executing interpolation. SOLUTION: Picture data obtained from a TV camera and the like are time-sequentially accumulated in a frame memory 3. A central arithmetic processing part 1 divides respective picture data at respective time into plural picture areas and calculates the motion vector of the respective picture points for the whole picture by using the local correlation method. A correlation arithmetic part 4 calculates the correlation value of picture data at time t1 and t2 after little time passes. The central arithmetic processing part 1 calculates the motion vector of the respective picture points of the picture and the reliability based on the correlation value and substitutes the motion vector of the picture point whose reliability does not satisfy a prescribed value for an interpolation vector for the respective divided picture areas.  The interpolation vector is synthesized by giving weight depending on the distance of the picture points to the motion vector of the picture point whose reliability satisfies the prescribed value.

Title: Arithmetic processor
Inventor: ISHII YOSHIHARU
IPC: G06F12/16
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To prevent the erroneous write of an SRAM by turning a CPU into a hold state and a reset state, and turning a static (S)RAM into a read/write state and a backup state when a power is decreased to a hold request voltage and a reset request voltage. SOLUTION: A main power supply voltage Vcc is supplied to a CPU 3, and an arithmetic operation is performed by a request arithmetic program. An SRAM 4 preserves data whose backup is necessary even after the interruption of the main power supply voltage among the arithmetic procession data. When the main power supply voltage Vcc is decreased to a hold request voltage, a memory backup IC2 completes a bus cycle which is being executed, stops the operation of the CPU 3, and turns it into a hold state. When the main power supply voltage is decreased to a reset request voltage, a system reset IC52 turns the CPU into a reset state, and switches the SRAM 4 from readable/ writable state to a backup state. Thus, the erroneous write of the data of the SRAM 4 can be prevented.
